3D Triangles Polygonal Mesh Conversion on 3D Spline Surfaces
Jahn, Zdeněk ; Šiler, Ondřej (referee) ; Kršek, Přemysl (advisor)
In computer graphics we can handle unstructured triangular 3D meshes which are not too usable for processing through their irregularity. In these situations it occurs need of conversion that 3D mesh to more suitable representation. Some kind of 3D spline surface can be proper alternative because it institutes regularity in the form of control points grid and that's why it is more suitable for next processing. During conversion, which is described in this thesis, quadrilateral 3D mesh is constructed at first. This mesh has regular structure but mainly the structure corresponds to structure of control points grid of resulting 3D spline surface. Created quadrilateral 3D mesh can be saved and consequently used in specific modeling applications for T-spline surface creation.

Prototype part and made by method rapid prototyping
Kočárek, Karel ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is dealing with prototype stage during development of reduction part for gas flow control, which is positioned in gas boiler downstream of the valve. Thesis is focused on additive manufacturing. Basic technologies, their attributes and procedures which are necessary to be followed are described here. Practical part is composed of 3D model creation in CAD software, export of model to STL format and its inspection for compactness. After that 3D model is sent to printer and functional components are made, that can be used for application verification and for detection of possible design deficiencies before the mold assembly is made.

CAD aplications in rapid prototyping
Pešek, Ondřej ; Madaj, Martin (referee) ; Zemčík, Oskar (advisor)
This thesis describes and compares the characteristics of CAD applications with respect to the use of rapid prototyping technology. The first part introduces the basic principles and methods of 3D printing technology and outlines current developments in this area. The second section describes the comparison CAD applications and their capabilities. The last section is devoted to key features of CAD systems. It is a comparison of available options, evaluation and recommendations.
